Rising knowledge - about the principle of solenoid valve of automobile air conditioning compressor

How much do you know about automobile air conditioning compressor? Why do automotive air conditioning compressors need solenoid valves? How does it work

First of all, the solenoid valve of automobile air conditioning compressor is an automatic basic element used to control fluid. It belongs to actuator and is not limited to hydraulic and pneumatic. Its working principle is that there are closed cavities in the solenoid valve and through holes are opened at different positions. Each hole leads to different oil pipes. In the middle of the cavity is a valve and there are two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is energized. Different oil discharge holes will be blocked or leaked by controlling the movement of the valve body, and the oil inlet hole is normally open, The hydraulic oil will enter different oil drain pipes, and then push the oil rigid piston through the oil pressure. The piston drives the piston rod, which drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.
